-;;; Commentary:
-
-;;; Org-Babel support for using ebnf2ps to generate encapsulated postscript
-;;; railroad diagrams. It recogises these arguments:
-;;;
-;;; :file is required; it must include the extension '.eps.' All the rules
-;;; in the block will be drawn in the same file. This is done by
-;;; inserting a '[<file>' comment at the start of the block (see the
-;;; documentation for ebnf-eps-buffer for more information).
-;;;
-;;; :style specifies a value in ebnf-style-database. This provides the
-;;; ability to customise the output. The style can also specify the
-;;; grammar syntax (by setting ebnf-syntax); note that only ebnf,
-;;; iso-ebnf, and yacc are supported by this file.
-
-;;; Requirements:
-
-;;; Code:
-(require 'ob)
-(require 'ebnf2ps)
-
-;; optionally declare default header arguments for this language
-(defvar org-babel-default-header-args:ebnf '((:style . nil)))
-
-;; Use ebnf-eps-buffer to produce an encapsulated postscript file.
